THEO Concept Mission: Testing the Habitability of Enceladus's Ocean [PDF]

, 2016
Saturn's moon Enceladus offers a unique opportunity in the search for life and habitable environments beyond Earth, a key theme of the National Research Council's 2013-2022 Decadal Survey. A plume of water vapor and ice spews from Enceladus's south polar region.

Particle‐Trapping Injection Flux Tubes in Saturn's Magnetosphere and High‐Band Electron Cyclotron Harmonic Waves Therein

Geophysical Research Letters, Volume 52, Issue 3, 16 February 2025.
Abstract Injection flux tubes, characterized by localized equatorial magnetic field enhancements and concomitant hot plasma populations, contribute to Saturn's magnetospheric convection cycle by transporting magnetic flux radially inward. The sharp magnetic gradients at the flux‐tube edges have been demonstrated to enable the trapping of equatorially ...

Formation of electron radiation belts at Saturn by Z-mode wave acceleration

Nature Communications, 2018
Radial diffusion is the only mechanism considered to accelerate trapped electrons to relativistic energies in Saturn’s magnetic field, forming radiation belts.

An exploratory first‐in‐man study to investigate the pharmacokinetics and safety of liposomal dexamethasone at a 2‐ and 1‐week interval in patients with metastatic castration resistant prostate cancer

Pharmacology Research & Perspectives, 2021
Dexamethasone has antitumor activity in metastatic castration resistant prostate cancer (mCRPC). We aimed to investigate intravenous liposome‐encapsulated dexamethasone disodium phosphate (liposomal dexamethasone) administration in mCRPC patients.

Orbital evolution of Saturn's mid-sized moons and the tidal heating of Enceladus [PDF]

, 2018
The formation and orbital evolution of Saturn's inner mid-sized moons are still debated. The most puzzling aspects are 1) how the Tethys-Dione pair and the Mimas-Enceladus pair passed through their strong 3:2 mean-motion resonances during the tidal orbital evolution, and 2) the current strong heat flow from Enceladus, which is a few orders of magnitude

One schema to rule them all: How Schema.org models the world of search

Journal of the Association for Information Science and Technology, Volume 76, Issue 2, Page 460-523, February 2025.
Abstract Several industry‐specific metadata initiatives have historically facilitated structured data modeling for the web in domains such as commerce, publishing, social media, and so forth. The metadata vocabularies produced by these initiatives allow developers to “wrap” information on the web to provide machine‐readable signals for search engines ...

Low Energy Subsurface Environments as Extraterrestrial Analogs

Frontiers in Microbiology, 2018
Earth’s subsurface is often isolated from phototrophic energy sources and characterized by chemotrophic modes of life. These environments are often oligotrophic and limited in electron donors or electron acceptors, and include continental crust ...

Dynamics of Enceladus and Dione inside the 2:1 Mean-Motion Resonance under Tidal Dissipation [PDF]

, 2008
In a previous work (Callegari and Yokoyama 2007, Celest. Mech. Dyn. Astr. vol. 98), the main features of the motion of the pair Enceladus-Dione were analyzed in the frozen regime, i.e., without considering the tidal evolution. Here, the results of a great deal of numerical simulations of a pair of satellites similar to Enceladus and Dione crossing the ...

The Plasma Proton Environment Within Saturn's F‐G Ring Gap as Observed by the Cassini Plasma Spectrometer Ion Mass Spectrometer During Saturn Orbit Insertion

Journal of Geophysical Research: Space Physics, Volume 130, Issue 2, February 2025.
Abstract We report on the detection of protons and the potential detection of H2+ between Saturn's F and G rings based on Cassini Plasma Spectrometer (CAPS) Ion Mass Spectrometer (IMS) time‐of‐flight (TOF) composition measurements acquired during Saturn Orbit Insertion (SOI) outbound pass. The range in dipole L shell is 2.3 < L < 2.8.

Gaia-Sausage-Enceladus star formation history as revealed by detailed elemental abundances [PDF]

A&A 691, A333 (2024)
The Gaia-Sausage-Enceladus merger was a major event in the history of the Milky Way. Studies on Milky Way satellite dwarf galaxies show that key elemental abundance patterns, which probe different nucleosynthetic channels, reflect the host galaxy's star formation history.
